摘 要: 利他行为可以分为亲缘利他、互惠利他与纯粹利他三种形式。对前两种利他行为,生物学已经给出了较为圆满的解释,而且,这种解释也是符合经济学原理的。关于纯粹利他,生物学存在着很大争论,至今没有圆满的解释。本文在“合作剩余”和“生物演化稳定策略”(ESS)的基础上,提出一个能够解释纯粹利他行为的模型,并利用脑科学的最新研究成果对这一行为内在的激励机制作出了说明。 Altruism can be divided into three sorts: relative altruism, bi lateral altruism and pure altruism. As to the first two forms of altruisms, the biology has put forward relatively satisfactory explanation. And these explanati ons also accord with economic principle. As to pure altruism, there are many deb ates in biology and lack satisfactory explanation till now. This article brings forward a model which can explain the pure altruism based on cooperative residua l and Ecological Stable Strategy(ESS), further explains the internal motivation mechanism for the behavior with the latest research results in brain science.
